Question

An 1N756 zener diode is used as a 12 V regulator in the circuit shown below: What is the smallest load resistor that can be used before losing regulation? Assume the ideal model for the zener diode

Answer 1

Answer:

Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage.
